" YBeit known that` I, ARTHUR H. Ws'roN,

siding at `jfloland, Park, 'Baltimore county, Maryland',liave'invented 'certain new and useful Improvements in Shoe-Blacking Stands, of which the following is a specification.

` The present invention relates to a shoe,l clamp and more particularlyto that type of clamp, one 'member of which actsfas a rest to support the foot-and the shoe thereon 1 foot" plate, a carrier mounted to move in a size of the particular' shoe.

^ )aw lever pivoted thereon, a locking surface Fig. l2, an enlargiged fragmentary elevation t ber forms an abutment again'stjj which "theA 5.5

clamp while the latter is being or repaired.

The clamp to be described, is lnirticularly i adapted to the use to which it is applied, in that it is automaticallyY locked and adj ustedv` to any size of'shoe. It grips the shoe securely and is "easily disengaged. It con# sists of few parts which may bel cheaply manufactured and of such proportions to be strong and. durable.

yMy device consists of a suitable frame, a

polished, cleaned predetermined path in relation' thereto, a

vadapted to cooperate with thej'aw and lock it when it engagesthe article to be clamped and means for moving the carriage 'to press' the jaws against the shoe. 4

An important feature of my invention is the locking jaw lever and locking surface, so arranged that when the jaw is advanced against a resistance, it is locked in each new position which vit occupies and cannot be withdrawn'until unlocked by reversal of the actuating meansf The number of positions in its path in which the. jawmay be locked is unlimited, so that the resulting pressure on the shoe is determined by the force ap-l plied to the actuating'lever-and not by the The drawings illustrate my invention. YFigure 1, is aside elevation of my device,

partly in section. Fig. 3, a perspective of the jaw lever and carrier. Fig. 4 1s a sectionl on line L -4, Fig. 2:

The shoe blacking` stand consistsl of 5 a frame 1 consisting Vof an upright web2, ay base Sand a foot plate 45.-. The foot plate. is shaped Ato supportja shoe ofanyusual size and is chambered at the rear at 5 to receive the heel. The forward wall 6' of the chamheelrests and acts as the fixed jaw Iofthe; which' is .to 'be described.v Below the Specicationof Letters Patent..

and substantially parallel tothel same, the web is provided with'w'ay's 7, one on each side of the web. Thecarrier 8 conf,

sists of parallel uprights'9 joined'by a horizontal-cross bar `10. Each upright is pro#` vided with a forwardly extending follower' o bar 11. These follower bars are parallel to cach other and adapted to engage and slide in the ways 7. p' The jaw lever 12 is provided at one end with a jaw. 13 adapted to engage the `heel of the shoe atl the rear and :it its opposite extremity with a downwardly disi posed locking surface 14. This lever is provided with a transversely extending pivot at a point intermediate of its length.4 This' pivot engages suitable journal bea-rings `1n thel upper extremities of' the uprights 9, so that the jaw lever swings between the latter with the jaw up and forwardly disposed.

The web 2 is provided intermediate the ways a v'I wit-lr a locking-member 15 which extends tothe rear parallel to the ways. This locking member is in the .forni of a straight har, its uppersurface 16 is flat and will be here inafter termed a lockingsurface. lVhenthe followers` ll'engage the ways 7, the locking member 15 extends to kthe rear betweenthc l uprights 9 above the cross bar land below' the locking 'lever 12. The least radius of the locking surface lll of the jaw lever,- measured from the center 23 about which that lever turns, is just equal to the distance from the center 23 to the :locking surface 16 of the member 15. An actuating lever 17 provided intermediately of its length with a transverse pivot.18 is mounted in suitable journal bearings 19 on the frame below 'the rear portion of the ways. The upper extremity of this lever is slotted at 20 to receive the transverse pin' 21 which is mounted in the lower extremities 22 of the nprights 9, extendingfrom one tothe other. The lower extremity of the lever 17 is adapted to be manually engaged.

ln the operation of my device, the shoe,

preferably on the foot, jis placed on the foot plate 4 .with the heel in the heel-chamber 5 and pressed against the abutment 6. The

lower extremity of the lever 17 is pressed to the rear, rotating the lever about' its, center 18, whereby the carrier Sis moved forward, the followers 11 sliding in -theways 7 The jaw 13 is broughtinto contact with the rear ofthe heel and rotated about its center 23.v

lockingsurface" ,14 into contact witv the the .'the center 23 increases in a direction oppol bination, a support for the one end of the jaw site to thatY of the rotation just described. Increased pressure'on -the long arm of the vlever 17 forces the locking surface of the lever into closer contact with thelocking 'surface of the frame and the two members become clamped in this posit-ion. The re sistance offered to backward pressure applied to thejaw increases withY that pressure. .Torelease the shoe, forward pressure is applied to the lower` arm of the lever 17. The carrier 8 moves tothe rear with but slight resistance, unlocking the lever 12.

Having thus described my invention, what .I claim and desire to secure by Letters Patent is:

1. In a stand for blaclcing shoes, in comshoe having a locking surface, an abutment, a carrier mounted on the support to move in a lixed path, a jaw member mounted on the carrier to move in a fixed path relatively thereto, and means for advancing the carrier to press member against the shoe and the other end againstthe locking surface.

2. In a stand for blaclring shoes in combination, a support for the shoe having a plane locking surface, an,I abutment'on the support, a vcarrier mounted on the support to' move in a fixed path relatively thereto, a 'Jaw lever pivotally mounted on the carrier and means for advancing the carrier to press one end of the jaw lever against the shoe and clamp the other end against the locking surface.

In a shoe clamp, a support for the shoe; lhaving a plane locking surface, an abut-ment on the support, a carrier mounted on the support to move in a iixed path relatively thereto, a lever pivotally mounted on the carrier having a jaw and a locking surface and means for advancing the carrier to press the jaw against the/shoe and the lock ing surface of the lever against the locking surface of the support.

4L. In a shoe clamp, in combination, a supportfor the shoe, an abutment on the support to prevent forward movement of the shoe, a carrier mount-ed on the support to slide in a fixed pat-h, a jaw member pivotally mounted on the carrier, the jaw member having a jaw and a locking surface, the radius of the locking surface of thejavv member, measuredfrom the pivot, increasing -in a direction opposite to that of the rotation caused by pressure ofthe shoe against the jaw, a locking member on the support having a plane lockingl surface, and means for advancing the carrier to press the avv against the shoe and the locking surface of the jaw member against the locking surface of the support.

In a shoe clamp, a support for the shoe, a carrier, a jaw lever pivotally mounted on the carrier, an abutment, a locking member on the support having a uniform locking surface and means for advancing the carrier against a resistance, whereby the jaw lever is made to cooperate with the locking surface and become locked against rearward movement in any position in which it meets the resistance; l
